Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31608132, here are decompositions:

41 + 31608091 = 31608132
71 + 31608061 = 31608132
103 + 31608029 = 31608132
163 + 31607969 = 31608132
211 + 31607921 = 31608132
223 + 31607909 = 31608132
229 + 31607903 = 31608132
263 + 31607869 = 31608132

Showing the first eight; more decompositions exist.
